The invention provides a nonaqueous electrolyte for batteries and a nonaqueous secondary battery using the same which maintains small internal resistance and high electric capacity in high temperature storage. The nonaqueous electrolyte has an electrolyte ...

The invention provides a nonaqueous secondary battery using a positive electrode containing a transition metal and lithium. The battery is prevented from deterioration due to elution of the transition metal from the positive electrode and thereby capable o...

Disclosed is a novel compound represented by formula (1) below. In the formula, A represents an optionally substituted aromatic hydrocarbon ring or aromatic heterocyclic group, B represents a group including a chain of one to four pieces of one or more gro...

The present invention provides a non-aqueous electrolyte secondary battery using a polyanion compound or a lithium nickelate as a positive electrode active material, which can maintain a small internal resistance and a high electric capacity even after und...

The present invention provides a non-aqueous electrolyte secondary battery using a lithium-containing metal oxide that contains manganese as a positive electrode active material, which can suppress the elution of manganese from the positive electrode activ...

Problem Provided are an additive for an electrolytic composition which can suppress the decrease of a short-circuit current and improve an open circuit voltage as compared to the case when conventional 4-TBpy is used as an additive for an electrolytic comp...

The present invention provides a non-aqueous electrolyte secondary battery that can improve the balance of the both of the output and capacity of the battery in the case when a negative electrode containing graphite particles having high crystallinity whic...
